Hi, there are a bunch of sites you can look into with no listing fees and low or no final sale fees.
In my personal experience, I had better luck on yardsellr and bonanza. Yardsellr has NO fees, so you get a much better profit than ebay. Bonanza only charge the final sale fees, but it is still much cheaper. I sold a pair of sunglasses for $130 and only had to pay $5.
